MANOVA, Chi Square, and correlations were used to analyze electrophysiologic and sonographic variables in limbs with divergent findings. CTS diagnosis was determined using EDX\u2010 and USI\u2010based classification systems, stratified by median nerve cross\u2010sectional area (CSA) cutoff values producing large conclusive or small questionable shifts in diagnostic probability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The proportion of limbs with a USI diagnosis of CTS but normal electrophysiologic findings was 17% and 35% when considering CSA cutoff values producing large conclusive and small questionable shifts in diagnostic probability, respectively. These limbs had significantly slower median sensory and motor latencies and larger distal and delta CSA compared to limbs with concordant findings. Conversely, the proportion of limbs with an EDX diagnosis of CTS but normal sonographic findings was 6% and 35% when considering CSA cutoff values producing large conclusive and small questionable shifts in diagnostic probability, respectively.
